The camera is a ZWO ASI120MC, and I was capturing using FireCapture v 2.4. The camera's full-frame resolution is 1280 x 960, but I was using a smaller ROI (Region Of Interest) framed around the target for each capture video.
For each capture, I would start by loading up FireCapture's default profile for the planet in question (this pre-loads some default exposure settings, etc), and then I would adjust the exposure until it looked "about right" on my computer's screen - I don't know whether my exposure settings (Gain / Exposure / Gamma) are anywhere near optimum for my rig.
Jupiter was typically shot with 5.5 ms exposures with gain at 50%, giving about 59 FPS on average (frames per second); Mars was shot at 2.8 ms (70 FPS); Saturn was 22.6 ms (43 FPS).
Actual capture frame-rate varied a bit between consecutive video captures - I think this is because this camera runs on a USB2.0 cable, and the data interface speed can be a limiting factor.
